Kept calling and got in touch, at like 3:05 est, parts should have shipped out for overnight delivery. I had to guess on the parts before troubleshooting with a tech and should have the right part for tomorrow.
The issue on the CH3 was everything went blank and stopped working - no more screen, can't move / print anything. Seems to be the 24v power supply died.
As for the phones mis-connecting, I have had that once before with M&R but usually get in touch finally.
Last time I called tech support I just stayed on the line instead of leaving the call back #.
